FOOTLIGHT DEVICE.

Application illed inne 11, 1927. vSerial No. 188,141.

The invention relates to foot-light devices used for lighting store windows or for similar purposes, of the type using incandescent tube-shaped lamps of which each end 1s l terminated by' a preferably cylindrical metallic cap connecte to the corresponding ends of the lamp filament so as to form the two poles thereof.

One object of the invention is to provide 7 an easy way for inserting or removing the lamp. A further object of the invention is to provide the possibility of installing footlights of any desired length without use. of any special strutting device, this being realized by the provision of a suitable number o supporting elements mounted in successive order according to the length of the lighting device which it is desired to establish.

i0 The annexed drawin of example two embodiments according to the invention. show a preferred form;` Figs. 1 and 2 show a support used for connecting the contiguous ends with like poles of two adjoining lamps, Fig. 1 being a front view, and Fig. 2 a section on line II-II Fig. 3) Fig. 3 is a lateral view of the footight built up by a series of successively arranged tubes, the l0 supporting elements being shown in sgction. Fi 4. is a lateral view showing the footli it on a reduced scale. y

igs. 5 and 6 illustrate another embodiment showing the device Aon a reduced scale in partial section, and lateral view respective Iny Figs. 1 to 4, 1 desi ates the wall whereto it is proposed to asten the footlight. 2, 2 2" are tube-shaped lamps comw prising each a luminous filament 3, the outer ends of which are electrically connected to two metallic caps 4 and 4'* respectively mounted u on the ends of the tube 2.

An insu ating member 5 with a hollow 6 provided in its art turned towards the wall 1, is iastene to the latter by any suitable means, such asI screws or the like. serted in this hollow I provide a longitudinal metallic plate 7 which is fixed to the 0 member 5 by a screw 9 in electrical contact with the plate 7, the latter comprising two illustrates by way of the device 'onction sockets 8 protruding into the mem-- r 5. A transverse bore.10, drilled in member 5, provides for the passage of the feed p wir 12, as ena of 'which heiligheid www.

' yunction a screw 11 and the aforesaid screw 9 whereby an electrical contact is established between said wire, said plate and the sockets 8.

. On the other hand, I can further provide another metallic sleeve 13 frictionally held vupon each metallic cap 4 and 4a respectively of every single lamp, this metallic sleeve 13 comprising a lug 14 adapted to be inserted and frictional y secured within one of said sockets 8; the sleeve 13 is enclosed within an insulating cap 15 with slot 16 providing a passage-wayl for the plug 14.

By suitable spacing and fastening two similar contacts such as 5 and 51 upon the wall 1, the electrical connection between the lamp and the feed wires 12 and 12 will be established by inserting upon both lamp ends the caps 13-15 and 13"---15il respectively, plugs 14.- and 14a being inserted into the corresponding sockets 8 and 8.a respectively. It is to be noted, both sockets 8 of each support being of like polarity, that the current will circulate in opposite directions in the twor lamps of a pair of adjoining lamps.

By providing a suitable number of suprts and lamps, a foot-light of any desired ength can be mounted without diiiiculties in any place. Instead foot-lights may also be mounted in broken lines, provided however that sulicient space be left between the two sockets 8 of a same support 5 to allow a lamp to be turned away at an angle from the adjoining one without interfering with their caps 15.

The junct'on parts 5, instead' of being separate, can be mounted in advance upon-a samesupport, made, as shown in Flgs. 5 and 6 by means of a U shaped metal bar. The construction shown in these gures is substantially the same as illustrated in the receding ones with the exception that the parts 5 are mounted within a rigid support 17 enclosing also the feed wires 12 and 12, The support used with this arrangement necessitates its previous assembly in the work shop according to the required length ofA the respective foot-lights, and its subsequent shipping to the place where it is to be used', whilepthe arrangement according to the preferred embodiment illustrated in Figs. 1 to 4, allows the mounting in place of foot-lights of any shape or length by using a corresponding number of separate arts 5 and lamps 2.

It is well understood that the embodiments of Astraight lines, the

`each metallic end cap, and a plu as illustrated and described hereabove are not limiting and that the constructive forms may be widely varied without departing from the scope of the invention.

I claim- 1. A foot-light device of the type using tube-shaped lamps of which both ends are closed by metallic caps connected to the corresponding ends of the lighting filament, comprising a series of separate supports, two metallic interconnected junction sockets in each of said supports, a common terminal connecting both said junction sockets to the feed wire, a conductor sleeve provided upon on each sleeve disposed for cooperation wlth one of said junction socke 2. A foot-light device of the type using tube-shaped lamps of which both ends are closed by metallic caps connected to the correspondlng ends of the lighting filament, comprising a series of separate supports, two metallic interconnected junction sockets in each of said supports, a common terminal connecting both said junction sockets to the feed wire, a conductor sleeve provided upon each metallic end cap, and a plug on each sleeve disposed for cooperation with one of said junction sockets, an insulating cap in-` serted upon saidconductor` sleeve, and a passage for the plug provided in said insulativ mg cap.

3. A foot-light device of the type-using tube-shaped lamps of which both ends are closed by metallic caps connected to the correspondlng ends of the lighting filament, comprising a series of separate supports, two metallic interconnected junction sockets in each of said supports, a common terminal connecting both said junction sockets to the feed wire-` a conductor sleeve provided upon each metallic end cap, and a plug on each sleeve disposed for cooperation with one of said junctlon sockets, saidseparate supports being independent from each other.

4. A foot-light device of the type ,using tube-shaped lamps of which each end is provided with a metallic cap connected to the corresponding end of t e lamp filament, comprlsing a number of supporting pieces made of insulating material and conformed to allow their fixation to any wall desired a hollow provided upon the inner face oi each of said su portin pieces, a metallic plate lodged witlim sai hollow,a junction socket extending through said insulating piece provided upon each end of said metallic plate, a terminal upon said plate connectlng the feed wire, atleast one transverse hole provided in said insulating support for the passage of the feed wire and its connection to said terminal, a metallic conductor sleeve mounted upon each of said end caps, plugs on the sleeves disposed for cooperation with said junction sockets, and an insulating cap inserted upon each of said conductor sleeves.

5. A support made of insulating material, comprisin atleast twolu ,a hole .provided in each o said lugs, a ho low upon the inner face of said support, a metallic plate lodged in said hollow, two connecting sockets provided u on said metallic plate extending througii said insulating support, a terminal provided on said plate connecting the feed wire, and atleast one transverseA hole in lsaid insulating piece leading to said termma In .testimony whereof, I have signed my name to this specification.
